A recent change made stat selectable exotics in World Versus World easily accesible. You’d have to play some WvW though to acquire the currencies.

In pve? Not too many. There are some achievements in LWS1 and LWS2 that give exotic trinkets, but some can only be done once per account.

Frankly, it would be easier to buy LW Season 3- specifically the Bitterfrost Frontier and Bloodstone Fen episodes and farm winterberries with different characters daily, which is enough for a new trinket every few days. All can be bought in Bitterfrost except the amulet, which you can get from Bloodstone Fen.

If you end up buying all of the living world seasons, The "Return To..." achievement offers a convenient way to work towards a legendary amulet while making enough map currency for ascended trinkets along the way.

You can get stat selectable exotic backpacks from the lunar New Year event. The backpacks are also on the TP.

Low-key, raid legendary armor is super easy to get (6 weeks of moderate investment, less if you have LI already, and you get a set of ascended armor halfway through for your troubles to gear a build of a diff armor weight since envoy1 isn't a precursor set) and makes gearing a whole host of builds waaaaayyyyy easier. Def been a big qol increase
